Nigeria is a high-burden country in terms of young people's health. Understanding changes in young people's sexual and reproductive health (SRH) behaviours and the associated factors is important for framing appropriate interventions.
This study assessed changes in SRH behaviours of unmarried young people aged 15-24 and associated factors over a ten-year period in Nigeria.
We analysed datasets from Nigeria Demographic and Health Surveys of 2008, 2013 and 2018 to assess changes in inconsistent condom use, non-use of modern contraceptives; multiple sexual partnership; and early sexual debut. Using binary logistic regression, we assessed the association of selected variables with the SRH behaviours.
Over four-fifths of unmarried young people (15-24) in Nigeria engaged in at least one risky sexual behaviour in each survey year. The pattern of changes in the four risky SRH behaviours was consistent over the 10-year period, with the highest rates of each behaviour occurring in 2018 while the lowest rates were in 2013, thus indicating an increase in the proportion of respondents engaging in risky sexual behaviours over the study period. Comprehensive HIV/AIDS knowledge, male gender, older age category (20-24), residence in south-west Nigeria, urban residence, higher socio-economic status, secondary/higher education were mostly protective against the four SRH variables analysed across the different data waves.
Addressing the high and increasing level of risky SRH behaviours among young people in Nigeria is imperative to improve overall national health status and to ensure progress towards achieving SDG target 3.7 focusing on SRH.
在年轻人健康方面，尼日利亚是一个负担沉重的国家。了解年轻人性行为和生殖健康（SRH）行为的变化及其相关因素对于制定适当的干预措施非常重要。
本研究评估了尼日利亚 10 年来未婚年轻人 15-24 岁的 SRH 行为变化及其相关因素。
我们分析了 2008 年、2013 年和 2018 年尼日利亚人口与健康调查的数据集，以评估不一致使用避孕套、不使用现代避孕药具、多个性伴侣和性早期开始等风险性行为的变化。使用二元逻辑回归，我们评估了选定变量与 SRH 行为的关联。
在每个调查年份，超过五分之四的尼日利亚未婚年轻人（15-24 岁）从事至少一种风险性行为。在 10 年期间，这四种危险的 SRH 行为的变化模式是一致的，每种行为的发生率在 2018 年最高，而在 2013 年最低，这表明在研究期间从事风险性行为的受访者比例有所增加。全面的艾滋病毒/艾滋病知识、男性性别、年龄较大（20-24 岁）、居住在西南部、城市居住、较高的社会经济地位、中学/高等教育在不同的数据波中对分析的四个 SRH 变量大多具有保护作用。
解决尼日利亚年轻人中高且不断增加的危险 SRH 行为问题对于改善整体国家健康状况和确保在实现关注 SRH 的可持续发展目标 3.7 方面取得进展至关重要。
